Osmoregulation

Front

What is osmoregulation?

Back

Control of water and salt in the body.

Front

What triggers the release of ADH from the pituitary gland?

Back

High blood concentration or low water potential in the blood.

Front

What are osmoreceptors?

Back

Cells that detect changes in blood concentration.

Front

What is the role of ADH in the kidneys?

Back

ADH makes the collecting duct more permeable to water, allowing for water reabsorption.

Front

What happens when you are over-hydrated?

Back

The body releases LESS ADH, making the collecting duct LESS permeable.

Front

Identify the structure labeled as the Collecting Duct.

Back

It is a part of the nephron where urine is concentrated.

Front

What is the function of the Distal Convoluted Tubule?

Back

It is involved in the reabsorption of sodium and water, and secretion of potassium and hydrogen.

Front

What is the primary hormone involved in osmoregulation?

Back

Antidiuretic hormone (ADH).

Front

Where is ADH released into?

Back

The circulatory system.

Front

What effect does dehydration have on ADH levels?

Back

Dehydration triggers the release of MORE ADH, increasing water reabsorption.
